Detailed description of the invention
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Suspension is the general name of all force transmission connections between vehicle frame (or self-supporting body) and vehicle bridge (or wheel).Suspension generally comprises elastic element, damping element, force transmission mechanism or is called guide frame and transverse arresting apparatus.Elastic element, such as spring 3000, can play buffer action, damping element, and such as shock absorber can play damping of vibrations, and force transmission mechanism plays power transmission and directional tagging, and transverse arresting apparatus prevents vehicle body from producing excessive inclination.
Can realize raising and reducing bodywork height by adjustment suspension.Referring to Fig. 1-Figure 24, the suspension elevating adjusting device 1000 according to the utility model embodiment is described.As shown in Fig. 1-Figure 24, comprise actuator 1 and transmission component 2 according to the suspension elevating adjusting device 1000 of the utility model embodiment.Actuator 1 is moved along the vertical direction by seat 2000 under transmission component 2 operating spring.
Be understandable that, spring lower seat 2000 is for support spring 3000, and spring 3000 can be arranged between spring lower seat 2000 and vehicle body, or spring 3000 can be supported between spring lower seat 2000 and vehicle bridge.Spring 3000 has rigidity, when the stressed timing of spring 3000, the length of spring 3000 is in the length of mating with this stressed size, and the length now due to spring 3000 is certain, thus change spring lower seat 2000 position in the vertical direction, vehicle body position in the vertical direction can be changed.
As shown in Figure 1, Figure 2 shown in 1 and Figure 22, transmission component 2 comprises the first Transmission 21, second Transmission 22 and the 3rd Transmission 23.
The axis of the first Transmission 21 is parallel with above-below direction, and the second Transmission 22 to be arranged under the driving of actuator 1 around the axial rotation of the first Transmission 21 and moving axially along the first Transmission 21, thus the second Transmission 22 promotes spring lower seat 2000 moves along the vertical direction.
That is, the second Transmission 22 around the axis of rotation extended along the vertical direction, can move along the vertical direction again under the driving of actuator 1, thus promotion spring lower seat 2000 moves along the vertical direction.
3rd Transmission 23 is arranged in and moves axially only support the second Transmission 22 around the axial rotation of the first Transmission 21 and along the first Transmission 21 under the driving of actuator 1, thus by the second Transmission 22 locking, by spring lower seat 2000 locking, thus ensure spring lower seat 2000 invariant position in vehicle travel process.
That is, 3rd Transmission 23 can around the axis of rotation extended along the vertical direction under the driving of actuator 1, can move along the vertical direction again, thus move to the position only supported with the second Transmission 22 by the second Transmission 22 locking, thus make spring lower seat 2000 be locked at desired location.
In brief, second Transmission 22 makes spring lower seat 2000 mobile to adjust vehicle body position along the vertical direction for supporting and promoting spring lower seat 2000,3rd Transmission 23 is for locking second Transmission 22, and spring lower seat 2000 is locked at desired location the most at last, finally realize the adjustment of bodywork height.
As shown in Figure 1, Figure 21, in some embodiments shown in Figure 22, the first Transmission 21 is stud, and the second Transmission 22 and the 3rd Transmission 23 are nut, and stud coordinates with nut thread, thus the low cost of manufacture of transmission component 2.The advantages such as in a preferred embodiment, stud can be provided with Acme thread, thus have good manufacturability, root of the tooth intensity is high, and centering is good.
Certainly, the way of realization of transmission component 2 is not limited to this, such as, in some preferred embodiments, first Transmission 21 can be ball-screw, second Transmission 22 and the 3rd Transmission 23 all can be configured to the ball nut coordinated with ball-screw, namely the first Transmission 21 and the second Transmission 22 and the first Transmission 21 and the 3rd Transmission 23 all can form ball guide screw nat, thus friction force between ball nut and ball-screw is little, relative motion is more smooth and easy, and then make the process of spring lower seat 2000 movement along the vertical direction without clamping stagnation and adjustment time more laborsaving.
Be understandable that, because the second Transmission 22 is for supporting and promoting spring lower seat 2000, the power of bearing is larger than the 3rd Transmission 23, thus, when the second Transmission 22 and the 3rd Transmission 23 are nut or ball nut, the thickness of the second Transmission 22 is greater than the thickness of the second Transmission 22.
When needing the position adjusting spring lower seat 2000, actuator 1 drives the second Transmission 22 that second Transmission 22 is rotated and moving axially along the first Transmission 21 around the first Transmission 21, when spring lower seat 2000 is adjusted to desired location, actuator 1 drives the 3rd Transmission 23 to rotate and axially moving towards the direction near the second Transmission 22 along the first Transmission 21 around the first Transmission 21 to make the 3rd Transmission 23, until the 3rd Transmission 23 only supports the second Transmission 22, thus spring lower seat 2000 is locked at desired location.Be understandable that, the locking principle of the 3rd Transmission 23 and the second Transmission 22 is that double nuts is stung tight mode and realized locking.
According to the suspension elevating adjusting device 1000 of the utility model embodiment, actuator 1 is moved along the vertical direction by seat 2000 under transmission component 2 operating spring, realize adjusting the object of spring lower seat 2000 in upper and lower position by actuator 1 with coordinating of transmission component 2, the position of vehicle body at above-below direction can be adjusted thus, realize raising or reducing of vehicle body, meet the traveling demand of vehicle in different road conditions, such as, when running at high speed, by reducing the height of vehicle body, windage can be reduced and promote manipulation stability, when vehicle travels on rugged road surface, the height of vehicle body can be raised, improve the ability of the leaping over obstacles of vehicle.
In addition, above-mentioned this suspension elevating adjusting device 1000, spring lower seat 2000 position is in the vertical direction adjusted with coordinating of transmission component 2 by actuator 1, the circumferential locations of spring 3000 can not be changed, namely when ensure that spring side force direction is constant, the position of seat 2000 vertical direction under regulating spring, thus realize the object raising or reduce bodywork height, the each hard spot (i.e. stress point) after shock absorber assembling can not be changed, this suspension elevating adjusting device 1000 also can be used for the suspension form of shock absorber without side force and shock absorber and spring 3000 split simultaneously, lower relative to air bellow cost, easier in B level, C level car is applied.
The suspension elevating adjusting device 1000 according to the utility model embodiment is described in detail referring to Fig. 1-Figure 24.Suspension elevating adjusting device 1000 as shown in Fig. 1-Figure 24 comprises actuator 1, transmission component 2, guidance set 3, locating part 41, first dust boot 43 and the second dust boot 44.
